The injured person was transported to Altru Health System with gunshot wounds, though it's not yet clear how extensive the injuries are, Zimmel told the Herald.

As of 9:15 a.m. Tuesday, that person was in “satisfactory condition,” according to a news release from the hospital.

A few minutes after 1 a.m., officers responded to discover “multiple victims,” who were taken to the hospital, Deputy Police Chief Mike Ferguson told the AP.

Zimmel said the 911 call mentioned multiple shots fired.

Andy Legg was in the store at the time of the shooting and told WDAZ he heard “popping sounds” in the store. As he was leaving, Legg said he saw a Walmart employee covered in blood, saying it “didn’t look good.”

Shortly after 4 a.m., a SWAT team began searching a car in the parking lot with a robot, according to the Herald.
